La Garenne Colombes, France Filed July 29, 1960, Ser. No. 46,269 6Claims. (Cl. 2131-195) This invention relates -to a smokers pipe.

The pipe made in accordance with this invention is characterized in thatit comprises an inner Ibowl arranged within an outer bowl, the contactpoint between the inner bowl and the outer bowl being reduced to a andproviding a passage around the inner bowl so that air is able tocirculate through the body of the outer bowl and escape through the topbetween the inner and outer bowls. In this way the inner bowl iscontinuously cooled, thereby making the pipe more pleasant to smoke.

ln accordance with a further characteristic of the invention, the pipelmouth piece is joined to the outer bowl by means of a stirrup shapedclamp, the middle part of which is engaged in -a `groove provided forthat purpose on the outer bowl, so that the mouth piece Iand the outerbowl are held securely in position while the ends of the stirrup areinserted into openings provided for the purpose in the front part of themouth piece on either side of the axial bore. A lilter is providedbetween Ithe mouth piece and the bowl which can be easily removed andreplaced without requiring the dismantling of the assembly; if desiredany suitable smoke cooling device can be substituted lfor this filter.

The accompanying drawings illustrate an embodiment of my invention givenby way of example only.

In the drawings:

FIGURE l is a fragmentary elevational view of the pipe, partially insection.

FIGURE 2 is a sectional view on line 2-2 of FlG. 1.

FIGURE .3 is an enlarged fragmentary View of the crown shown at the topof FIG. l.

The tobacco pipe shown in FIGURE 1 comprises a mouth piece 3 having atubular extension 30 axially arranged with a smoke passage therethroughso as to provide an extension of said passage 'and has a yieldingplastic portion 28 thereon.

The pipe bowl assembly comprises an outer bowl 38 preferably made ofmolded plastic and an inner bowl 37 preferably made of a refractorymaterial. The inner bowl is spaced from the outer bowl and held inspaced relationship therewith by means of a crown 40. rl'his crown hasupwardly extending tabs or lugs 41 which are received by and held inythe under portion yof a circular metal piece 39, which piece isretained under and holds the upper lip of the inner bowl. 'Ihe bottomportion of the inner bowl 'flits within a recess in the bottom portionof the outer bowl and is held in spaced relation therewith by means of aspacing ring 43, which rests rupon the radially inwardly displacedportion at the bottom part of said outer bowl. This ring has openings 44therein to allow the circulation of air upwardly. The outer bowl hasholes 22, 22 in the bottom thereof. A circular groove is molded into alower radially inwardly `displaced portion of said outer bowl whichgroove receives a stirrup 12 which stirrup has two rearwardly projectingrods which lare in the same horizontal plane with the shank 32. Thestirnup is received within the openings formed within the mouth pieceand holds the mouth piece in rigid assembly with the outer bowl. A holeformed through the bottom of said outer bowl and connected with anopening in the inner bowl has a tubular extension 31. Arranged on theouter portion of this tubular extension is a yielding plastic portion29. Adjacent thereto is a shoulder 35.

3,091,246 Patented May 28, 1963 ICC The shank 32 is so arranged Ithatthe opening 36 in one end of it will receive and be held in smoke-tightengagement with the tubular extension 30 by means of Ithe plasticelement 28. The opening 34 in the other end receives and is held insmoke-tight engagement with the tubular extension 31. The shoulder 33 isprovided on the end of this ltubular element which contacts the portion29 and prevents the forward motion of the shank. The shank 32 may besupplied with outer cooling iins and with an inner spring (not shown).

In operation, air is admitted through the openings 22 in the bottom ofthe outer bowl, which air circulates upwardly between the yinner bowl 37and the outer bowl 3S passing through the openings 44 in the spacerelement 43. This lair cools the inner bowl 37 and passes upwardly andoutwardly between the inner bowl and the crown and is vented at theunder side of the crown. The shank may be removed by simply sliding theshank towards the mouth piece until the shank will clear the tubularextension 31, where it may be lowered and removed for cleaning. Theshank may be replaced by sliding the rear end of the shank over theplastic portion 28 over the tubular extension 30 and then when it tisaligned with the tubular extension 31 it is forced towards the bowluntil the shoulder 33 contacts the face portion of the tubular extension31 and the plastic element 29 holds itin smoke-tight relationshiptherewith.

What I claim is:

1. A tobacco pipe including a mouth piece, a bowl and a shank connectingthe mouth piece to the bowl, the shank comprising a hollow tubularelement 'having a smoke duct therein and a pair of members divergingoutwardly from said tubular element and from the mouth piece toward thebowl, the outer end of said members being joined to said bowl, said bowlcomprising an outer bowl part, and an inner bowl part spaced inwardlyfrom said -outer bowl part, said outer bowl having at least one holevformed through the bottom thereof, la crown carrying the upperoutwardly ilaring edge of the inner bowl and overlying the upper edge ofthe outer bowl and 'a washer carrying said crown by means of resilientlugs and maintaining the upper portion of the inner bowl centered in theouter bowl, said outer bowl having a radially inwardly displaced portionproviding an internal Shoulder adapted to seat a bottom washer tomaintain the lower portion of said inner bowl in spaced relation to saidouter bowl.

2. A tobacco pipe as claimed in claim 1, wherein said shank comprises abowl portion and a mouth piece portion rigidly iixed thereto, eachportion having a sealing means thereon Iat an end thereof, said sealingmeans receiving and holding an intermediate tubular element removablyconnecting said bowl portion and said mouth piece portion.

3. A Itobacco pipe including a mouth piece, a bowl having a circularsection and a shank connecting the mouth piece to the bowl, the shankcomprising a hollow tubular element having a smoke duct therein, and apair of members diverging outwardly from said tubular element and fromthe mouth piece toward the bowl, the outer end of said members beingjoined by means of a semi-circular portion, said :members and saidportions comprising a stirrup, said bowl comprising an outer bowl part,and an inner bowl part spaced inwardly from said outer bowl part, saidouter bowl having lat least one hole formed through the bottom thereof,a crown carrying the upper outwardly iiaring edge of ythe inner bowl andoverlying the upper edge of the outer bowl and Ia washer carrying saidcrown by means of resilient lugs and maintaining the upper portion ofthe inner bowl centered in the outer bowl, the lower pontion of theouter bowl having a horizontal external groove therearound `adapted toreceive said stirrup semi-circular portion, said outer bowl Y 3 havingla radially inwardly displaced portion from said external groove andproviding an internal shoulder adapted to seat a 'bottom fwasher tomaintain the 'lower portion of said inner Ibowl in spaced relation tosaid outer bowl.

4. A tobacco pipe las claimed in claim 3, wherein said 5 gro'ove portionprovides an opening for the shank to the inner bowl so that the hollowtube and the diverging stirrup members to have their longitudinal axesin the same horizontal plane.

5.
